How do you calculate Ka value?

Chemists determine the strength of an acid (Ka) by measuring the concentrations of HA, H 30 + and A – at equilibrium and dividing the concentrations of the products by the concentration of the original acid. Because the concentration of water is a constant, they leave it out of the equation. Ka = [H 3O +] [A -]/[HA]

Why are Ka values all small numbers?

Almost all Ka values in general are smaller numbers. The reason is that K values represent very weak acids.

Does high Ka mean stronger acid?

Thus this means that a High Ka means a “strong” weak acid and a low Ka means a “weak” weak acid. And the pKa is the same but contradicting. High pKa means “weak” weak acid and low pKa means “strong” weak acid. The same goes for Kb and pKb but just for base. Ka and Kb are usually large numbers, and as to create smaller numbers we use pKa and pKb.

What is the equation for Ka?

The numerical value of Ka is used to predict the extent of acid dissociation. A large Ka value indicates a stronger acid (more of the acid dissociates) and small Ka value indicates a weaker acid (less of the acid dissociates). For a chemical equation of the form HA + H2O ⇋ H3O + + A −
